Abstract :

A system that is available only once is called a one-shot system. To ensure its high availability, an inspection is performed regularly because its failure is detected only through it. In this paper, we discuss management policies in replacement timings of a single-unit one-shot system whose failures are removed by minimal repairs. We compare the two replacement policies that manages the number of failures and the number of periodic inspections. Our objective is to compare the two management policies of replacement timings by formulating the incurred cost rate, which is cost per unit time, and the availability.
